Castro has been on the injured list since Sept. 5 due to left heel plantar fasciitis and right knee soreness, and rather than attempting to ramp back up with the hope of playing in the final week and a half of the season, he's instead elected to shut himself down. After joining the Rockies on a two-year deal over the winter, the 29-year-old slashed .260/.331/.417 with 15 home runs, 10 stolen bases, 65 runs and 56 RBI in 120 games during his first season in Colorado.

Although Dollander managed to avoid undergoing a full Tommy John procedure, the operation will still put an early end to his second MLB season. He showed significant improvement in 2026, turning in a 3.89 ERA and 1.30 WHIP alongside a 47:18 K:BB in 44 innings across 10 appearances (three starts). A clearer timeline for his return could emerge as the 2027 campaign approaches.

Colorado placed Herrera on the 15-day injured list Friday due to left elbow inflammation, but he was shifted to the 60-day IL just two days later after a follow-up MRI apparently revealed that the 22-year-old reliever was dealing with ligament damage. Schaeffer said that the Rockies don't currently have a timeline for Herrera to go under the knife, as the left-hander will presumably receive additional medical evaluations before deciding whether to get Tommy John surgery, an internal brace procedure or a hybrid of the two. Even if Herrera avoids a UCL reconstruction and instead has a UCL repair surgery, he's still likely to require close to a full year of rehab and recovery before returning to game action in the middle or second half of the 2027 season.

The Rockies have yet to officially confirm whether Brown was able to complete the next step in his throwing program, but at the very least, the report presumably indicates that the right-hander has already thrown off a mound without a hitter present in the batter's box. Brown has been on the mend from right shoulder inflammation since the early weeks of spring training, and given how long he's been shelved, he'll likely need to complete multiple live sessions before moving on to what will presumably be an extended minor-league rehab assignment. The 26-year-old has three minor-league options remaining and could be sent to Triple-A Albuquerque or Double-A Hartford once he's deemed ready to return from the 60-day injured list.

Petit will miss the entire 2026 campaign after undergoing Tommy John surgery with an internal brace on his right elbow last week. Valente Bellozo was selected to the 40-man roster and optioned to Triple-A Albuquerque in a corresponding move.

Ohl underwent season-ending Tommy John surgery in late February. If the Rockies bring him back as a reliever, he has a chance to be ready in time for the start of next season.

The 34-year-old is dealing with a lumbar degenerative disc disease and has played a combined 170 games across four seasons since inking a seven-year, $182 million contract with Colorado. Bryant was placed on the 60-day injured list last week, and there's been no indicate of when, or if, he'll be able to retake the field.

Meidroth will get another day off to recover from a hamstring issue that's been bothering him as the White Sox aim to get him as healthy as possible for the postseason. Sam Antonacci will start at second base as a result, opening up left field for Randal Grichuk.

Rogers will step away from the team for its final couple of regular-season games as he welcomes a new addition to his family, but he'll be back by the time the White Sox begin their postseason run. Until then, Drew Romo will come up from Triple-A to provide depth at catcher.

Castillo posted a 7.52 ERA in six starts and then a 13.50 ERA in three relief outings after being demoted to the Chicago bullpen. The veteran right-hander will be eligible for activation during the ALDS, but considering how he's pitched, there's a good chance Castillo's season is over even if he's healthy.

Berroa has been on the injured list all season while working his way back from Tommy John surgery and a setback he suffered while pitching in the Arizona Complex League. He was cleared to resume throwing in early July, and although his progress has been slow, the White Sox haven't ruled out a return for the 26-year-old before the end of the season.

Bush has spent the entire season on the 60-day injured list while recovering from Tommy John surgery that he underwent in February. He was cleared to resume throwing in early July, but he has since suffered a setback that will keep him on the shelf for the rest of the 2026 season. Bush will turn his focus toward being fully healthy for the start of the 2027 campaign.

Leasure will miss the remainder of this season and likely all of next season while on the mend. Fegan notes that the right-hander hopes to be ready for spring of 2028. Leasure landed on the injured list in late May with a right flexor strain, and while he had been cleared to resume throwing side sessions at the beginning of August, it was ultimately determined that he needed to go under the knife to repair his UCL.

Bart's hand was hit by a pitch during Thursday's game against Boston. The veteran catcher is set to be sidelined until at least mid-September, and how he progresses in his recovery program will determine whether he'll be back in action with the White Sox before the conclusion of the 2026 season. With Kyle Teel also sidelined until at least September due to a left high-ankle sprain, Drew Romo and Edgar Quero will handle catching duties for the White Sox moving forward.

The move clears a spot on the 40-man roster for outfielder Dustin Harris, who was called up from Triple-A Charlotte. Vasil underwent Tommy John surgery in March and will be sidelined until around the middle of the 2027 season.

The move opens up a spot on the 40-man roster for Randal Grichuk, who signed a one-year major-league deal with the White Sox on Monday. Murray suffered a left shoulder dislocation and fracture while making a diving catch in left field against the Nationals in late April. His recovery timeline was initially set at 4-to-6 months, which means he won't be available to return until at least late August.

The transaction is merely a formality, as Baldwin is already slated to miss the rest of the season after undergoing internal brace surgery on his right elbow last Wednesday. The utility player will cede his spot on the White Sox's 40-man roster to left-hander Tyler Schweitzer, who was called up from Triple-A Charlotte.
